Recently had to change the screen on my sisters laptop, it had lines running down all over the place. I replaced it, all of a few minutes work, just a few little screws and one wire unplug/replug. The screen itself cost just over £100 (about just over $150ish). That was a 17", LCD backlit, not HD screen and was packard bell, so will probably be roughly the same price.
If you plan on doing it yourself then i would recomend getting a watch makers set of screwdrivers or something similar if you don't already, we are talking VERY small screws here.
If you are getting someone else to do it, labour charges are massive, you are looking at possibly $50-100 more
